Context: I've never used Overtone before, but I've heard of it. I came across this today and decided to do it during my lunch break.
Here's a brain dump of thoughts I had during my first hour or so of playing with Overtone.
Installation was really awesome. One line in project.clj, lein deps and it just worked. Definitely a great start.

After typing on my new Realforce 103UB for a few hours, here are my first impressions.
(other good keyboards I've used: Das Silent, Das Ultimate, HHKB Pro 2)
My initial thought on taking it out of the box was that it felt really sleek. Thin almost. It feels way slimmer than the Dases do in my hands. It think it's a consequence of the rounded edge compared to the Das' sharp, square edges, much like Macbooks have the rounded edges to feel thinner.
Once you put it on the table though, it turns into a beast. It's very wide and flat. Here it is compared to the HHKB I was using before:
Let's say I make a piece of Clojure code that does something other than serve a website.
Example: a loop that checks twitter every 10 minutes for mentions of some product and emails them to me. You'd start it with lein run and it would run until killed, (Thread/sleep 1000)ing when it doesn't need to work.
Can I host this kind of thing, standalone, on Heroku? With the free plan?
So far it seems like the answer is yes. I just name it something other than 'web' in the procfile (so Heroku doesn't expect it to bind to a port) and then scale it to one process. So the procfile looks like:
